[0003] The composite board forming production line includes key equipment such as unwinding machine, preheating equipment, foaming machine, material distribution machine, double-crawler machine, and cut-to-length machine. The unwinding machine supports the steel coil by tightening the inner hole of the steel coil, and then rotates to send the head of the steel strip to the subsequent sheet forming equipment with the cooperation of the straightening machine. The preheating equipment is used for the lower layer of material transportation and heating of metal coils, aluminum foil, glass fiber cloth, and non-woven fabrics. The foaming machine mixes the components in the required proportion and sprays them evenly between the lower steel plate or other substrates. The material distribution machine realizes the uniform arrangement of raw materials for various core materials. The double-crawler machine ensures the bonding force of the sheet and assists and controls the expansion of the foaming structure to ensure the best polymerization reaction, which is used to ensure the thickness and flatness of the sheet during transportation. The cut-to-length machine saws the formed sheet into the set size.

[0032] like Figure 1-4 As shown, a plate positioning offset detection mechanism for a composite plate forming machine includes a fixed base 1, a baffle mounting seat 3, a detection baffle 4 and a laser displacement sensor 5.

[0033] The fixed base 1 is installed on both sides of the frame of any device between two forming devices. The fixed base 1 is a square plate, which is fixed on both sides of the frame of the plate forming device by bolts.

[0034] The baffle mounting seat 3 is arranged above the fixed base 1 for mounting the detection baffle 4. Specifically, the baffle mounting seat 3 is provided with a long hole, and the fixed base 1 is provided with a threaded hole, which is fixed by bolts passing through the long hole and the threaded hole.

[0035] like Figure 2As shown, the right end of the detection baffle 4 is a square plate, the left end of the detection baffle 4 is tilted outward, the detection baffle 4 is rotatably connected to the baffle mounting seat 3, the detection baffle 4 is vertically arranged and the length direction of the detection baffle 4 is parallel to the forward direction of the sheet forming equipment production line, and one side of the detection baffle 4 is in contact with the side of the sheet. Specifically, a rotating shaft 6 is arranged on one side of the left end of the detection baffle 4, the rotating shaft 6 is connected to the detection baffle 4 by welding, and the bottom of the rotating shaft 6 of the detection baffle 4 is connected to the baffle mounting seat 3 by a second bearing 12, and the second bearing 12 is fixed in the hole of the baffle mounting seat 3 by a retaining spring.

[0036] A reset element 7 is provided between the detection baffle 4 and the baffle mounting seat 3, and is used for resetting the detection baffle 4 after the baffle 4 is offset. Specifically, the reset element 7 is a spring or a torsion spring. When the reset element 7 is a torsion spring, the torsion spring is sleeved on the rotating shaft 6, one support arm of the torsion spring is fixedly connected to a side surface of the detection baffle 4, and the other support arm of the torsion spring is fixedly connected to the upper end surface of the baffle mounting seat 3; when the reset element 7 is a spring, one end of the spring is hung on the rear end of the detection baffle 4, and the other end of the spring is hung on the baffle mounting seat 3.

[0037] The laser displacement sensor 5 is disposed on the other side of the detection baffle 4 . The laser displacement sensor 5 is used to measure the offset distance of the detection baffle 4 . The laser displacement sensor 5 is installed on the fixed base 1 .

[0038] The laser displacement sensor 5 is a non-contact laser displacement sensor or a contact laser displacement sensor. Preferably, the non-contact laser displacement sensor model is TQGJS-2011; the contact laser displacement sensor model is GT2-H12.

[0039] A further solution of the present invention is that the laser displacement sensor 5 is provided with a display screen and an indicator light, the display screen is used to display the displacement data collected in real time, and the indicator light is used to indicate whether the measured displacement data exceeds a set range.

[0040] The principle and circuit connection of the laser displacement sensor 5 are prior art. Those skilled in the art can implement this technical solution according to the model and circuit connection of the equipment, and this patent will not describe it further.

[0041] Example 2

[0042] This embodiment is based on Embodiment 1, and a further solution is that, in order to adjust the distance between the laser sensor and the detection baffle 4, the laser displacement sensor 5 is arranged on the sensor mounting seat 2, the sensor mounting seat 2 is a square plate, and the sensor mounting seat 2 is installed on the fixed base 1 through a fine-tuning mechanism 8, and the fine-tuning mechanism 8 is used to adjust the distance between the laser displacement sensor 5 and the detection baffle 4.

[0043] Specifically, the fine-tuning mechanism 8 includes a guide base 13, a lead screw 14 and a slider 15.

[0047] According to the above embodiment, taking the detection mechanism 300 between the unwinding machine 100 and the preheating device 100 as an example, the detection mechanism 300 is installed on both sides of the left end of the preheating device 400 to detect whether the steel plate unwinding from the unwinding machine 100 is offset. First, according to the width of the plate 200, the position of the detection baffle 4 and the position of the laser displacement sensor 5 are adjusted, and the laser displacement sensor 5 is calibrated.

[0048] The steel plate enters the preheating equipment from the left end. When the plate 200 is offset, the plate will squeeze the detection baffle 4 and rotate along the rotating shaft 6 at a certain angle. The laser displacement sensor 5 detects that the distance between the detection baffle 4 and the laser displacement sensor 5 changes. When the plate is offset to a certain extent and reaches the maximum or minimum threshold set by the laser displacement sensor 5, an alarm indication signal is issued. Through manual intervention, the unwinding angle of the unwinding machine is adjusted to avoid a large offset of the plate when it enters the preheating equipment again, thereby ensuring the quality of subsequent processed products.

[0049] This detection mechanism is also applicable to the connection between the preheating equipment and the foaming machine, between the foaming machine and the material distribution machine, between the material distribution machine and the double-track machine, and between the double-track machine and the cut-to-length cutting machine.
